The present study focuses on the development of datasets characterizing the neutron field generated by the collimation channel of the Prizm-AN irradiation stand, which utilizes an internal bounded neutron (IBN) radioisotope capsule as a fast neutron source. It is aimed at supporting the prototyping of the proposed Thermal Neutron Imaging System (TENIS) diagnostics framework, currently in the feasibility assessment phase. To this end, comprehensive calculations of the radiation fields and dose characteristics associated with the Prizm-AN system-tailored to the operational specifics of the TENIS equipment-are presented. These insights will be valuable for developers in the preparatory stages leading to the creation of a demonstration version of the system. Additionally, the study explores the potential application of detection technologies for the real-time monitoring and control of parameters related to leaking deuterium-tritium (d-t) plasma.
